This invention relates to a device of the kind to receive written and graphic matter and presenting a plurality (at least two) of independent superposed and relatively slidable writing ot" 5 drawing surfaces.

The invention has for its object so to improve this class of device that the markings on the said surfaces formed as a totality can be analysed into details or partial details, and these so combined or positioned relatively to one another that all the detailsof the markings can be viewed at the same time in juxtaposition.

This eiect is obtained by a device including at least two independent superposed surfaces capable of being written o-r drawn upon and slidable relatively to one another, which is characterised by an abutment plate carrying strips capable of being written on and overlapping one another after the manner of shingles, and a slide guided in a frame and carrying strips capable of being written or drawn upon and likewise overlapping one another in the manner of shingles and secured to the slide at the top and bottom edges, but otherwise loose, so that between the slide and the loose parts of the second mentioned strips there are left gaps for passage of the first mentioned strips.

The invention is illustrated by way of example in one embodiment in the accompanying draw- Fig. 1 shows in elevation as a detail an abutment plate with a set of associated strips formed as surfaces capable of being written on.

Fig. 2 is a section on the line II-II of Fig. 1 showing the shingle-like overlapping of the strips.

Fig. 3 shows in elevation as a detail a set of strips formed as surfaces to be written or drawn upon with millimetric sub-divisions into squares. 40 Fig. 4 is a section on the line IV-IV of Fig. 3 and shows the shingle-like overlapping of the strips of Fig. 3.

Fig. 5 shows to a larger scale in elevation the parts illustrated in Figs. 1 to 4 united to form a complete device in the three operative positions of the device obtainable by the adjustment of the slide.

Fig. 6 is a section on the line VI-VI of Fig. 5.

Fig. 'l furnishes a diagrammatic representa- 50 tion of the relative position of the strips in the complete device.

In the drawing the invention is illustrated as an example of construction representing by numerals and graphically economic statistics.

On a xed base plate I (Fig. 6) there is secured an abutment plate 2 shown in Fig. 1 in detail and xedly fitted in a frame 3 (Fig. 5). The plate 2 carries writing surfaces 4 which are secured Vonly along one edge to the plate and are so arranged that they overlap one another after the manner of shingles (Fig. 2). In the embodiment illustrated these surfaces consist of paper strips 4. The first strip 4 is broader than the remaining strips 4, which latter are all of the same breadth, in order to provide a larger 10 writing surface for special entries. The strips 4 are lined and bear designations of the month. Further, each strip 4 is divided midway by a ne hair line 5 which serves as a boundary line for the inscription on the right hand half of the strips.

6 represents a slide provided with a hand rail 'I and slidably guided in the frame 3. The displacement to the left is limited by the plate 2 and to the right by the frame 3. On the slide are also secured surfaces 8 of paper which overlap one another after the manner of shingles in the same way as to the strips 4. In Fig. 4 the shingle-like overlapping of the strips 8 is shown in diagrammatic form by dash lines. In contrast with the strips 4, the strips 8 are secured to the slide only at the top and bottom edges at 9 and I0 (Fig. 3), so that between the slide and the loose parts of the several strips 8 there are provided passages. In the example illustrated the strips 8 are ruled into squares to facilitate the graphic representation in the form of curves.

The plate I with its strips 4 and the slide 6 with its strips 8 are arranged within the frame 3 in the manner indicated in Fig. 6; that is, the 35 slide lies on the baseplate I and the strips 4 pass through the several passages presented by the strips 8 in the manner indicated diagrammatically in Fig. '7.

This relative arrangement of the plate I and 40 of the slide 6 with the appertaining strips 4 and 8 ensures that on shift of the slide 6 into its left hand end position (position I of Fig. 5), the strips 8 disappear entirely beneath the strips 4 and the subdivisions of the strips 8 are no longer visible. 45 The strips 4 form in their totality a unitary writing surface. If the slide is moved to the right up to the hair lines 5, then each of the strips 4 and 8 becomes visible as to one half (position 2 of Fig. 5) There are now presented two writing 50 surfaces, one with the lines ruled on the strips 4 and one with the squares of the strips 8 disposed alongside one another. If, finally, the slide is moved to the right into its end position, the strips 8 make entirely the strips 4 lying beneath u them and appear over their full breadth, so that the drawing surface is now a unitary writing surface with millimetric squares or sub-divisions (position 3 of Fig. 5).

The significance of this arrangement of the abutment plate and of the slide and of their different possibilities of adjustment relatively to one another appears from the representation according to Fig. 5. From the position I it appears that on the writing surface formed by the totality of the strips 4, entries in the form of numerals can be effected. To these entries there correspond the curves drawn on the surface formed by the totality of the strips 8. When the slide is shifted into position 2 of Fig. 5, the markings on the writing surfaces and drawing surfaces are analysed into individual representations and so combined with one another or positioned relatively to one another that both sets of markings appear directly alongside one another and each written entry can be considered and cornpared with its appertaining graphic representation.

As material for the construction of the device there may be employed cardboard, aluminium, wood, or other material.

The form and sub-division of the surfaces of the strips 4 and 8 may be as desired. These strips may be plain washable writing surfaces; they may be provided with sub-divisions or the like, and may be contrived for writing on or drawing on with any material used for Writing or drawing.

We claim:

1. A recording and graph device comprising in combination a frame, an abutting plate xedly mounted within said frame, a base sheet secured to said abutting plate, overlapping strips of paper secured at one of their longitudinal edges to said base sheet, a slide plate slidingly mounted in said frame, overlapping strips of paper secured at their top and bottom edges to said slide plate so as to form slots therebetween, said slide plate being arranged within said frame in such a way that said strips of paper secured to said base sheet are interposed in said slots and the sliding movement of said slide plate being limited in one direction by said abutting plate and in the other direction by said frame.

2. A recording and graph device comprising in combination a frame, an abutting plate located within said frame, a base sheet secured to said plate, overlapping strips secured by one of their longitudinal edges to said base sheet, said strips being made of a material capable of being written on, a slide plate slidingly mounted in said frame, overlapping strips secured to said slide plate at their top and bottom edges so as to form slots, said slide plate being arranged Within said frame so that said strips on said base sheet are interposed in said slots and means limiting relative movement between said strips.

3. A recording and graph device as set forth in claim 1 in which said strips secured to said slide plate are overlapped to such an extent as to prevent disengagement between said strips during their relative movement.
